782 REPORT OF THE HARVARD AFRICAN EXPEDITION 
twice the length of second, fourth slightly longer than second, tips scarcely dilated; hind limbs long 
and slender; toes without trace of web, very long and slender; the tibio-tarsal articulation of the 
adpressed hind limb reaches the nostril. Skin, above and below, smooth and glistening. 
Coloration. — Above dark slate, almost black; posterior aspect of thigh with (in alcohol) a 
fine white line or series of elongate spots; on the anterior aspect of each thigh close to body, a 
white spot. Belly dark slate, with a coarse net work of anastomosing narrow white lines. Lower 
aspects of hind limbs white, abundantly spotted or blotched with dull brown; feet and hands 
banded or spotted with dark brown or white. 
Measurements. — Snout to vent, 22; length of head, 6.5; breadth of head, 6.5; diameter of 
orbit, 3; length of tibia, 12; length of foot, 16; length of fourth toe, 9 mm. 
Leptopelis tessmanni Nieden 
2 ex. (M.C.Z. 12000-1) Ghanga. 
2 ex. (M.C.Z. 12002-3) Plantation No. 3, Du River. 
These specimens agree very closely with Nieden’s description except in size, 
the largest of these being only 42 mm. and the smallest 12 mm. Probably all 
are immature. They are not, however, identical with Leptopelis tessmanni of 
Noble from the Congo. We have carefully examined two of his Medje specimens 
and find them identical with L. aubryi of which we have a large series from the 
Cameroons. Why Dr. Noble should consider the absence of a dorso-lateral line 
a character of L. rufus is difficult to say as most East African L. rufus have such 
a line and these were carefully compared with similar specimens in the British 
Museum. 
Hylambates hyloides Boulenger 
1 ex. (M.C.Z. 11942) Paiata, St. Paul’s River. 
1 ex. (M.C.Z. 11943) Moala. 
1 ex. (M.C.Z. 11944) Gbhanga. 
Megalixalus immaculatus Boulenger 
1 ex. (M.C.Z. 12035) Bonuta. 
Structurally this 834 mm. frog agrees well with the species, though the tym- 
panum is hidden. In alcohol it is uniformly blackish above. Color in life. 
“Mottled green and yellowish above.” Formerly known from Spanish Guinea 
and French Congo. 
Megalixalus fulvovittatus (Cope) 
2 ex. (M.C.Z. 12024—5) Plantation No. 3, Du River. 
1 ex. (M.C.Z. 12026) Ghanga. 
These are topotypes in that only ‘Liberia’ is given for the type locality. 
M. vittiger (Peters) 1s undoubtedly a synonym. There are numerous minute 
black spines on the hind limbs of the male, a sexual character which assists in 
separating this species from leptosomus which it so closely resembles in color 
pattern. In leptosomus the hind limbs of both species are alike. The female is 
badly infected with some dermal (?dipterous) parasite that leaves swellings with 
central craters. There are eight of these around the anus, one on the right tibia, 
two on left flank and a twelfth in front of left foreleg. The male has one on the 
underside of its right thigh and several about the anus.
